Abstract
A snow thrower includes a rotor assembly having a first auger, a second auger, and a paddle disposed between the first and second augers. The snow thrower also includes an intake housing having a first interior surface adjacent to the first auger and a second interior surface adjacent to the second auger, where an outer edge of the first auger has a clearance of less than 1 centimeter from the first interior surface across a sweep of at least 120 degrees, and an outer edge of the second auger has a clearance of less than 1 centimeter from the second interior surface across a sweep of at least 120 degrees.

A snow thrower comprising:
- a rotor assembly having a first auger, a second auger, and a paddle disposed between the first and second augers, the rotor assembly fixed to a shaft and the shaft configured to rotate around an axis;
- an intake housing having a first interior surface adjacent to the first auger and a second interior surface adjacent to the second auger, the intake housing further comprising a first kicker and a second kicker defining a chute opening therebetween, the chute opening having a width greater than a width of a throwing surface of the rotor assembly;
- wherein an outer edge of the first auger has a clearance of less than 1 centimeter from the first interior surface, wherein the first interior surface extends from a bottom edge to a corner edge of the intake housing, and an outer edge of the second auger has a clearance of less than 1 centimeter from the second interior surface, wherein the second interior surface extends from a bottom edge to a corner edge of the intake housing.
A snow thrower comprising:
- a rotor assembly having a first auger, a second auger, and a paddle disposed between the first and second augers, the rotor assembly fixed to a shaft and the shaft configured to rotate around an axis;
- an intake housing having a first interior surface adjacent to the first auger and a second interior surface adjacent to the second auger, the intake housing further comprising a first kicker and a second kicker defining a chute opening therebetween,
- wherein an outer edge of the first auger has a clearance of less than 1 centimeter from the first interior surface across a sweep of at least 120 degrees, and an outer edge of the second auger has a clearance of less than 1 centimeter from the second interior surface across a sweep of at least 120 degrees.
A snow thrower comprising:
- an intake housing comprising a first kicker and a second kicker defining a chute opening therebetween;
- and
- a rotor assembly having a first auger, a second auger, and a paddle disposed between the first and second augers, the rotor assembly fixed to a shaft and the shaft configured to rotate around an axis;
- wherein the paddle comprises:
- a throwing surface;
- a first opening configured to receive the first auger;
- and
- a second opening configured to receive the second auger;
- the first auger having a leading end adjacent to a first side of the intake housing, a trailing end adjoining the throwing surface, and a conveying surface extending between the leading end and the trailing end;
- and
- the second auger having a leading end adjacent to a second side of the intake housing, a trailing end adjoining the throwing surface, and a conveying surface extending between the leading end and the trailing end.
